AUTOMATIC STARTING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 681,048, dated August 20, 1901.

Application filed January 30, 1901. Serial No. 45,336. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE V. ELLIs, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Automatic Starting Apparatus, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide a fluid-operated starting device for all classes of machinery. I]Ih. ...f9rm here shown is esqpecially adapted-to, starting the ejector or fdrainage-tanks -isystems of sewerage.

other pump used 0 clear out cesspools and It is obvious also that the invention could be adapted to various other purposes which will make themselves apparent as this description tion.

progresses.

t This specification is the disclosure of one form of the invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a schematic view of my inven- Fig. 2 is an enlarged vertical section showing the construction of the various parts.

Fig. 3 is a plan view, with parts in section, illustrating the device for throwing the threeway cock and also illustrating the lost move- .ment involved in the operation thereof; and

Fig. 4is an enlarged section of a part of the apparatus to be hereinafter more fully described.

Referring to Fig. 1, let it be assumed that a represents a pipe carrying fluid under pressure; I), a pipe leading from the drainage- 1 tank which is to be pumped out; 0, an ejector or other form of pump, and d a dischargepipe; also, let 6 represent a smallerpipe havin the cylinder g. The parts in this cylinder are arranged to hold the valve h closed when such parts are under the action of the fluid from the pipes e and 2. When the cock f is thrown, it closes the communication between the pipes e and e and places the drain f in communication with the branch pipe e. This relieves the pressure within the cylinder g, and the valve h by the action of a spring or its equivalent may then move to open position, permitting the fluid within the pipe Ct to operate the ejector or pump 0, and thus draw the liquid from the drainage-tank up through the pipe I? and out through the pipe d.

Referring to Fig. 2, the valve h carries on its casing a frame h, which sustains the cylinder g. To the valve is connected a stem 7L2, which passes up into the cylinder and forms the rod of the piston g, working in the cylinder. This piston is normally pressed upward, so as to open the valve h, by a spring 9 situated in the cylinder, and projecting upwardly from the piston g is a rigid rod 9 which Works through the upper head of the cylinder and into a part of the pipe 6', so as to guide the movement of the piston. This rod 9 is provided with one or more grooves 9 which constitute by-passes and enable the free passage of the fluid into the cylinder 9, notwithstanding that therod g enters the only orifice through which the fluid may reach the cylinder. Fig. 2 is supposed to show the parts under the action. of the fluid-pressure from the pipe 6, and in this View the piston gis moved down sufficiently to seatthe valve h and close the pipe (1. When this pressure is relieved, the spring 9 asserts itself, and the valve h is thereby opened.

It will be apparent that since there is fora great part of the time a constant pressure of fluid above the piston g there will be a tendency to fluid leakage past the piston. To avoid a packing-box around the rod 11 at the bottom of the cylinder, I provide a sleeve g which is fastened to the lower end of the cylinder and projects upward in the cylinder around the rod W. The rod carries a knob 71?, which may be eitherfastened to or formed integral therewith and which when the piston and 'rod are in the position shown in Fig. 2 will bear on the upper end of the sleeve 9 thus closing it and hermetically sealing the lower end of the cylinder.

The three-way cockf comprises a casing in which is fitted a plug. f having three ports therein, as shown in Fig. 2, one port registering with the pipe e, another with the pipe e, and the third with the drain-nozzle f. When the cock is thrown, as shown in Fig. 2, the pipes e and e are in communication with each other; but when the plug is turned so as to cut oi the pipe e communication is then formed between the plugf and the pipe e, and therefore when the plug is so turned the fluid-pressure from the pipe 6 is not only cut ofi, but the pipe 6 is opened to the atmosphere, and through this pipe the upper end of the cylinder 9 is opened to the atmosphere, thus relieving the pressure in the cylinder and permitting the spring g to perform its oflice.

The three-way cock 1 may be operated by any means desired. If this invention is used in connection with a drainage-tank and like appliances, it is preferable for obvious reasons to operate the cock by a float. I have here shown a construction adapted to that purpose. The plugf of the cockfhas both of its ends connected with a yoke t', furnished with a disk-like head 7 rigidly connected thereto, the yoket'spanning the casing of the cock f. A casing i loosely embraces the disk t" and is held pivotally thereon by a pin i and this casing has attached thereto an arm '8, which is adapted to be connected with the float-rod. (Not shown.) The casing t is formed with two lips i thereon, which are op- By adjusting these screws 2' the loose movement of the casing '1? on the disk 11 may be regulated to the required degree. Owing to the curvature of the arm 15 and its attached parts the casing 2' normally hangs in the position shown in Figs. 1 and 2-that is to say, it hangs downward, its free movement being arrested by the lower screw t engaging on the under side of the yoke i. As the float begins to move upward its first movement is lost in the idle movement of the casing i on the disk 41, and movement is not imparted to the yoke 41 until the upper setscrew d bears on the yoke, and then the parts 2" and i will be rendered rigid, so that the further movement of the float will impart a movement to the yoke 2', thus throwing the plugf of the cock f. The purpose of this arrangement is to regulate the time when the apparatus is to be started to clear out a drainagetank. Obviously it is not desirable to start the pumping operation the instant that liquid accumulates in the drainage-tank. It is this may be regulated to the required degree by adjusting the set-screws W, as explained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. An automatic starting apparatus, comprising a pipe, a valve commanding the same, a cylinder, a piston working therein and having connection with the valve to actuate it, a device tending to move the valve into open position, and means for applying a fluid-pres sure to the piston so as to move the valve against the tendency of said device, for the purpose specified.

An automatic starting apparatus, having a cylinder, a piston therein, a piston-rod connected with the piston and adapted to transmit the movement thereof to a valve, a device tending to push the piston in one direction, and means for applying fluid-pressure to the piston to hold it against the tendency of the said device.

3. An automatic starting apparatus,'having a cylinder, a piston working therein, a piston-rod connected with the cylinder and adapted to transmit the movement thereof, a

device tending to move the piston in one direction, means serving to apply fluid-pressure to the piston to move it against the tendency of the said device, and a three-way cock for commanding the said means and comprising a drain-orifice to open the cylinder to the atmosphere upon the cutting 01f of the fluidsupply.

In an automatic starting apparatus, a valve, a cylinder, a piston in the cylinder and operatively connected with the valve, means for controlling the admission of a fluid to the cylinder to cause the piston to hold the valve closed, and means for moving the piston in an opposite direction to that which it is moved by the fluid-pressure when the cylinder is relieved of fluid-pressure, as and for the purpose set forth.
